Abstract: A method is taught to alleviate some of the expected seawater corrosion of aluminum alloy fuel tanks originating from the chlorides present in seawater through the use of a dicarboxylic acid additive that is added to the aluminum alloy fuel tank when seawater enters the tank.

Abstract: The present invention relates to a method for eliminating surface irregulties on the wraparound window of a torpedo nose array. The method broadly comprises the steps of preheating an oven to a temperature in the range of from about room temperature to about 160.degree. F., placing the nose array with the surface irregularities in the preheated oven, applying a vacuum at a pressure of up to about 10 mm of mercury, and maintaining the object in the oven under the conditions of temperature and pressure for a time sufficient to cause polymerization at the surface of the object and removal of gas bubbles, waves and blisters from the surface of the nose array. The method further comprises introducing an anhydrous gas such as nitrogen into the oven during the vacuum applying step.

Abstract: A process is provided for treating the solid reaction by-products of lith and sulfur hexafluoride. Lithium in the by-product solid waste is converted to lithium hydroxide. Lithium sulfide in the by-product is converted to lithium hydroxide. Lithium sulfide in the by-product is reacted with an acid to form a water soluble salt and hydrogen sulfide. The hydrogen sulfide is converted to an alkali metal sulfate. Solid aluminum oxide and lithium fluoride are recovered as a feed in the production of aluminum. Remaining lithium salts in solution are converted to lithium carbonate.

Abstract: A gas/liquid separator which includes a hollow cylindrical separator body ving: 1) an inlet port for receiving a tangential inflow of a gas/liquid mixture, and 2) an outlet port for allowing liquid separated from the mixture to tangentially exit the cylindrical separator body. The inlet port and outlet port are located such that they face 90.degree. apart from one another. A hollow cylindrical vortex finder is positioned concentrically within the cylindrical separator body which allows the primary and secondary gas flows to exit as stipulated.

Abstract: A gas/liquid separator system has an outer enclosing tank filled with a dsting packing material. The tank has a gas outlet port and a liquid outlet port located at its top and bottom, respectively. At least one cylindrical, centrifugal force gas/liquid separator is vertically aligned and centrally located within the tank and is surrounded by the packing material. The cylindrical separator receives a gas/liquid mixture, separates the mixture into respective substantially gas and substantially liquid components, and allows the substantially gas components to exit its gas escape port and the substantially liquid components to exit its liquid escape port. The packing material in the tank further separates the substantially gas and liquid components as they rise and fall, respectively, through the packing material. An inflow line introduces the mixture into the cylindrical separator.

Abstract: A method of electroless plating together with electroless plating solutions for plating the substrate of a transition metal capable of forming metal peroxides such as molybdenum or tungsten with a layer of metal plate such as chromium, cobalt, nickel or rhodium. The plating process features an oxidation and reduction reaction in which unstable surface oxides on the substrate of the transition metal are replaced by the desired metal plate. The method of the invention provides an oxygen impervious plate which protects against oxidation of the metal substrate and eliminates oxide migration as well as providing an improved metal-to-metal plate bond.
